Prove that thickness of k17-{one edge} is 3 or 4?

k17-{one edge} has 135 edges

Expert Solution

The thickness of a graph G, denoted θ(G), is the
smallest number of planar subgraphs into which G can be decomposed.
That is, find the optimal way to partition of the edge set of G into disjoint subsets, each of which is a planar graph.
So if G is planar, θ(G) = 1, and if G is non-planar, cr(G) ≥ 2.

Thickness of K17 is 4.

A graph consists of nodes and edges. An edge is an (unordered) pair of two distinct nodes in the graph. We create a new empty graph from the class Graph. We use the add_node method to add a single node and the add_nodes method to add multiple nodes. Nodes are identified by unique symbols. We call add_edge with two nodes to add an edge between a pair of nodes belonging to the graph. We can also ask a graph for...

The thickness of a cardboard sheet has a normal distribution with a mean of 3 cm and a standard deviation of 0.1 cm. 60 of these sheets are stacked on top of each other to transport to the next operation in the process. a) Determine the probability distribution for the total height of the stack of 60 cardboard sheets. Give the name of the distribution and its parameter(s). b) The trailer used to transport the cardboards sheets has a capacity...

1. Prove that for any graph, the sum the degreesPv∈V deg(v) is twice the number of edges |E|. (By “prove” I mean write a few sentences explaining why it is true.) 2. i) At a recent math seminar, 5 mathematicians greeted each other by shaking hands. Is it possible for each mathematician to shake hands with exactly 3 other people? (No one can shake his or her own hand.) To answer the question, please rephrase the problem as a problem about...
